HATCHWAY-GUARD.

SPECIFICATION forming part of Letters Patent No. 228,747, dated June 15, 1880.

Application filed February 12, 1880.

To all whom it may concern:

Be it known that I, WILLIAM I. ELY, of Detroit, county of WVayne, State of Michigan, have invented a new and useful Improvement in Hatchway Guards; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a new and useful improvement in hatchway-guards; and it consists in a gateso connected with a compoundlever arrangement that as the elevator rises the elevator itself, or a suitable arm located thereon, will, by impinging against the-compound lever, cause the guard to rise either on the ascent or descent of the elevator, as will be hereinafter more particularly specified, and pointed out in the claims.

In the drawings, Figure l is a view, in elevation, of a hatchwayguard embodying my invention, with the gate or guard closed; Fig. 2, the same, with the elevator acting to lift the guard as the former rises, and showing the elevator in dotted lines acting in like manner to raise the guard or gate as the elevator is descending.

A is any suitable freight or passenger elevator. B are its ways or guides. O is the hatchway gate or guard. This gate or guard consists of an arm, 0, pivoted to a support at c. A bar, 0 is suspended loosely from the bar 0 by the arms 0 D is a lever, pivoted at d to a support. E is another lever, pivoted at e to a support. The lever E has an arm projecting out, so as to come in contact with the carin its descent. The opposite end of the lever is, by a connecting-rod, E united with the lever D, as shown. One end of the lever 1) projects out, so as to be struck by the car in its ascent, while the other end of the lever is, by a connecting-rod, E united to the leverarm 0 of the gate 0. F is a part of the framework of the car, or it may be an arm attached to the car.

The operation of the device will be readily understood from the drawings. The car A in ascending brings its arm E into contact with the end of the lever D. As it turns this lever about its pivotal point (Z its opposite end will draw down upon the connecting-rod E and that, acting upon the lever-arm c of the gate 0, will lift the gate up into a vertical position, and

the lower bar, 0 will fold up vertically by gravity. At the same time that the gate is being elevated the connecting-rod E will lift upon the outer end of the lever E, and will cause that end which is adjacent to the elevator-well to drop down, so as to be out of the way of the car in its ascent. When, however, the car shall have passed up beyond the lever D, the lever E will, by the gravity of the gate, be brought against the arm E, and will follow up beneath the car as it rises, and in that way permit the gate to drop gradually down, so as to close the passage.

On the descent of the elevator the operation is reversed. The elevator will first impinge against the end of the lever E, and by press ing that lever down will lift the gate and bring the lever D up out of the way of the car. As the car passes on down, the lever D will follow in upon the top of the arm F, thus causing the gate to drop down gradually into its place.

WVhat I claim is- 1. The combination, with a guard or gate, of the lever and connecting-rod D E for opening the same, and, in connection therewith, a lever and connecting-rod, E E, for causing the gate to close gradually as the car ascends, substantially as and for the purposes described. v

2. The compound-lever mechanism consisting of levers D and E, with connecting-rods E and E so constructed that the movement of the free ends of the lovers toward each other, either in the ascent or descent of the elevator, would operate to open the hatchway gate or guard, substantially as and for the purposes described.

3. The combination, with the car or cage of an elevator, provided with arm F, or its equivalent, of the hatchway gate or guard, and compound-lever mechanism, consisting of levers D and E and connecting-rods E E said compound-lever mechanism being arranged and constructed so that the free ends of said levers will be forced toward each other either in the ascent 0r descent of the car or cage, and open the hatchway gate or guard, substantially as set forth.

In testimony whereof I sign this specification in the presence of two witnesses.
